Publication number: 20230082692Abstract: Apparatus and method of locating and/or counting one or more surgical articles, wherein the surgical article may comprise a surgical sponge comprising a counting element and/or detecting element. The counting element and/or detecting element may comprise an RFID tag encapsulated in a housing or pouch that is coupled to the surgical sponge. The RFID tag may further comprise unique identification and/or location information relative to the surgical sponge. The RFID tag may be coupled to the sponge at an attachment position and/or oriented on the surgical sponge relative to a defined set of reference lines. The attachment position and/or orientation of the RFID tag on the surgical sponge may be configured to improve the accuracy of scanning the RFID tag. A plurality of surgical articles (i.e. surgical sponges) comprising RFID tags may be packaged or bundled via a strap or within a container.Type: ApplicationFiled: November 22, 2022Publication date: March 16, 2023Applicant: Stryker CorporationInventors: Fazel Yavari, Glen David Rocque, Justin Andrews, Brian James VanDerWoude, Grant Westphal, Nathan Hogan, Skylar Lee Clark

Publication number: 20220142621Abstract: A waste collection cart assembly for collecting waste material from a suction line during a medical procedure. The waste collection cart assembly includes a housing having a top portion defining a work surface. A waste container is coupled to the housing for collecting the waste material from the suction line. A manifold receiver defining an opening is coupled to the waste container. A manifold having a specimen trap is received within the opening of the manifold receiver. A vacuum source is coupled to the waste container. The vacuum source provides a vacuum on the waste container to draw the waste material from the suction line through the manifold and into the waste container. The specimen trap collects a specimen from the waste material while being drawn into the waste container. The specimen may be transferred to a specimen container disposed on the work surface.Type: ApplicationFiled: April 11, 2020Publication date: May 12, 2022Applicant: Stryker CorporationInventors: Michael Zollinger, Jacob C. Foor, Chamara L. Gamhewage, Brian MacLachlan, Peter LaDuke, Rachel Wallace, Michael Hammond, Fernando Erismann, Brooke Mason, Noah Needler, Michael Peterson, Caitlynn Roy, Grant Westphal

Publication number: 20210379525Abstract: A waste collection unit for collecting waste material. A reservoir is supported on a portable cart for storing a liquid on the portable cart when positioned away from a docking station. A sprinkler may be coupled to the waste container and in fluid communication with the reservoir. The sprinkler is configured to direct the liquid from the reservoir towards the waste container. The reservoir is configured to receive additional liquid from the docking station to urge the liquid from the reservoir towards the sprinkler. A prefill pump may be supported on the portable cart and in fluid communication with the waste container and operable to convey the liquid from the reservoir to the waste container. A controller may be in electronic communication with a valve assembly to control flow of the liquid from the docking station into at least one of the reservoir and a second waste container.Type: ApplicationFiled: August 25, 2021Publication date: December 9, 2021Applicant: Stryker CorporationInventors: Brent S. Lalomia, Stephen J. Reasoner, Stephen Isham, Chamara L. Gamhewage, Mark A. Wasserman, Glen D. Rocque, Troy E. Durnell, Grant Westphal, Brian MacLachlan

Patent number: 11130089Abstract: A waste collection unit for collecting waste material. First and second waste containers are supported on a portable cart. A control panel is configured to receive one or more inputs of selectively set vacuum levels in the first and/or second waste containers. A control system controls operation of vacuum regulators based on the input(s) to regulate levels of vacuums being drawn in each of the waste containers. Pressure sensors in communication with the control system may be positioned to monitor pressure in the waste containers. A back up port support on the portable cart may be provided to receive a vacuum line for coupling a vacuum manifold to a remote vacuum source not located on the portable cart. Container lamps may be coupled to the first and/or second waste containers and configured to illuminate the waste material within the waste containers to be viewed through transparent windows.Type: GrantFiled: November 2, 2018Date of Patent: September 28, 2021Assignee: Stryker CorporationInventors: Brent S. Lalomia, Stephen J. Reasoner, Stephen Isham, Chamara L. Gamhewage, Mark A. Wasserman, Glen D. Rocque, Troy E. Durnell, Grant Westphal, Brian MacLachlan

Publication number: 20070135779Abstract: A waste collection and disposal system for use in health care facilities is provided. The system includes a mobile waste collection unit for moving between use areas in the health care facility to collect waste material generated during medical procedures including body fluids, body tissues, saline, etc. The waste collection unit includes stacked upper and lower waste containers for receiving the waste material. During use, the upper waste container can be emptied into the lower waste container for temporary storage. In addition, different vacuum levels can be provided in the waste containers during complex procedures. Once a user desires to empty the waste collection unit, the waste collection unit is wheeled to a docking station. At the docking station, the waste material is off-loaded to a waste drain and the waste collection unit is cleaned and rinsed for further use.Type: ApplicationFiled: December 13, 2006Publication date: June 14, 2007Applicant: STRYKER CORPORATIONInventors: Brent Lalomia, Stephen Reasoner, Stephen Isham, Chamara Gamhewage, Mark Wasserman, Glen Rocque, Sean Murray, Troy Durnell, Grant Westphal, Joseph Hepp, Brian MacLachlan, Brandon Scanlon
